quick question about ide driver


In my boot messages i have the following line:

ide: Assuming 33Mhz system bus speed for PIO modes; override\ with idebus=xx

Now for my assumtions:
the 33Mhz is ide speed (I have a UDMA133 controller).
So I should override with: idebus=133
and I'm assuming that idebus=133 is a kernel argument that i will just add to lilo.conf where I have: hdd=ide-scsi

does this all sound right to you or am i about overclock something to death?

thanks

i wondered about this myself

hdparm enables dma

i think i'm right in saying that PIO mode is like DOS level
and so would be expected to be 33mhz

there are several good threads on this in this forum

Never really found out what PIO is exactly.
